Alameda County supervisors hope new negotiations between the county, the city of Oakland and a development firm yield a plan to keep all three Oakland sports teams at the existing Oakland Coliseum site without spending taxpayer money on stadium construction, the supervisors said at their meeting Tuesday.

The 49ers and Raiders have made so many changes this offseason that even A’s GM Billy Beane is impressed. But what do all of the player moves and coaching changes mean for each team’s chances of holding the Lombardi Trophy at Levi’s Stadium next February?

Oakland City Council members unanimously voted to approve an exclusive negotiating agreement to build the proposed Coliseum City project. It could be the step needed to keep the A’s, and Raiders in the East Bay.
